Yes, you cannot hope ever to understand the difference between potential 
and actual infinity.

In actual infinity all numbers are present. No one is missing, according 
to Cantor. None can be added.
If you multiply every number by 2, then larger even numbers than all 
hitherto present even numbers are created because the number of numbers 
remains constant but the odd numbers disappear.
